That's not what this is and you know it. The equivalent would imagining a fictional world where we could say just raise the dead or Borderland's style instantly print you a new body at the phone-booth down the street. In that world there's no point to murdering you, they get no benefit it's only an inconvenience to the person being murdered.

In that world you need very little actual protection against murder because there's no incentive to do it. That's the current state of iPhones, you don't need to lock them up, use those chest pickpocket proof bags, or strap them to your wrist because no one wants to steal them.
